DISK-SORAPING MECHANISM.

Specification of Letters Patent.

Patented. Nov. 20, 1906.

Original application filed. January 30, 1 90 6, Serial No. 298,6 8 9.Divided and this application filed May 18,1906 Serial No. 31 7,5 '79.

To all whom it may concern.-

Beit known that I, IRA JAMES KAAR, a resident of Havelock, in the countyof Lancaster and State of Nebraska, have invented certain new and usefulImprovements in Disk-Scraping Mechanism and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enableothers skilled in the art to which it appertains tomake and use the same.

My invention relates to improvements in disk-scraping mechanism, thisapplication being a division of application filedJanuary 30, 1906, anddesignated by Serial No. 298,689, Patent No. 825,466, the object of theinvention being to provide improved mounting and operating mechanism forscrapers to clean two or more pairs of disks; and the invention consistsin certain novel features of construction and combinations andarrangements of parts as will be more fully hereinafter described, andpointed out in the claims.

The accompanying drawing is a view in front elevation illustrating myimprovements.

1 represents a section of frame serving as a support for a notchedsegment 2, and a vertica ever 3 is pivoted between its ends to thesegment 2 and provided with a detent 4 to engage the segment and lockthe lever at any adjustment.

5 and 6 represent parallel longitudinallymovable rods, the formerconnected by a link 7 with lever 3 above the pivotal point of the latterand the rod 6 connected by a link 8 with the lower end of lever 3. Tothe ends of these rods 5 and 6 arms 9 are loosely secured and carryscrapers 10 at their lower ends to engage the concave faces of disks 11to clean them, and it will be seen that by moving the lever 3 all of thescrapers will be simultaneously moved toward or away from all of thedisks, as the case may be.

A great many slight changes might be made in the general form andarrangement of the parts described without departing from my invention,and hence I do not restrict myself to the precise details set forth, but

consider myself at liberty to make such slight changes and alterationsas fairly fall within the s irit and scope of my invention.

Having fufiy described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. The combination with supporting means, of two longitudinally-movablerods mounted therein side by side, a lever mounted on the supportbetween the ends of said rods, connections between the lever and rodsfor moving the latter longitudinally in opposite directions, scrapersand rigid connections between said rods and scrapers.

, 2. The combination with supporting means and twolongitudinally-movable rods mounted therein side by side and extendingin both directions from said support, scrapers having rigid connectionwith the respective ends of each rod, a lever pivoted between its endsto said support, and links connecting said rods with the lever atrespective sides of the fulcrum of the latter.

3. The combination with a support and two longitudinally-movable rodsmounted therein side by side, each of said rods projecting beyond theadjacent end of-the other rod, of a scraper carried by and movable witheach of said rods and means for moving said rods simultaneously inreverse directions.

4. The combination withsupportingmeans and two longitudinally-movablerods mounted therein side by side, each rod projecting beyond theadjacent end of the other rod, of scrapers carried by the respectiveends of said rods, a vertically-disposed lever pivoted between its endsto said su port, a link connecting one of said rods wit h the leverbelow the pivotal support of the latter and a link connecting the otherrod with the lever above the pivotal support of the latter.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
